GAS-BURNER.

Specicaton of Letters .'Patent No. 14,091, dated January 15, 1856.

To all whom t may concern Be it known that we, CHARLES A. CUM- MINGS and CORTLAND DoUGnAss, of New London, in the county of New London and State of Connecticut, have invented a new and useful Improvement in Gas-Burners; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figures l and 2 exhibit central sections at right angles to each other on an enlarged scale of a fish-tail burner with our improvement applied. Fig. 3, is a top view of the same. Fig. at, is a central section of a similar burner with the improvement applied in a different manner, and Fig. 5, a top view of the same.

Similar letters of reference indicate corresponding parts in the several ligures.

This invention is applicable to what are known as fish tail burners or to other burners from which two jets of gas issue toward each other. It consists in interposing a metal plate between the two orifices from which the gas issues, in such a manner that the two jets or streams of gas issuing therefrom will strike it on opposite sides and be spread into a broad sheet. This plate becomes highly heated and serves as a heat reserver by which the gas is heated so as to produce a very perfect combustion and it spreads the gas into a broader sheet than when the two jets or streams are spread by simply meeting each other and thereby gives a better light thus in two ways effecting a saving in the consumption of gas.

To enable others skilled in the art to make and use our invention we will proceed to describe the manner of applying the same.

In the several figures a, a, are the orifices from which issue the two jets of gas, and is the interposed plate which constitutes our improvement. This plate is made of any metal not easily oxidized or corroded,

Aand may be of about one-fortieth of an inch 'so as not to interfere with the orices a, a,

and in Figs. Lland 5, it is represented as being secured to an elastic split metal collar d, which fits tightly over the top of the burner. Either of the above modes of applying the plate to the burner may be adopted with equal success but the last described mode possesses the advantage of enabling it to be applied to any burner already in use without removing it. It is probable that other modes o' applying the plate may also be employed and therefore we do not limit ourselves to those methods of applying it. In Fig. 8, the plate is represented in dotted outline for the purpose of making the notches c, c, visible in bold outline.

What we claim as our invention and desire to secure by Letters Patent, is,

The interposition between two jets or streams of gas issuing from the same burner, of a plate substantially as and for the purposes herein set forth.
